What Happens When You Put an AI Dev Team on a Mac Mini?

I built a local AI agent development team on a Mac Mini to support software development for HausHavn, a real estate workflow platform. Instead of using AI for one-off prompts, I set up separate agents with clear roles across architecture, coding, QA, product analysis, documentation, and project management. The demo shows how I orchestrate those agents through real development work, including task handoffs, code review, GitHub issues, Notion sync, release QA, and the messy lessons of making agents useful as process infrastructure, not magic.
